Add component error tracking and web UI display

[springfall2008]

Summary

This PR adds comprehensive error tracking for all Predbat components with visual display in the web UI.

Changes

Component Base Class (component_base.py)

• Added get_error_count() method to return error count for each component
• Enhanced error handling in start() loop to call non_fatal_error_occurred() on failures
• Added non_fatal_error_occurred() method to notify base system of errors
• Error counter (count_errors) is incremented on both run failures and exceptions

Components Class (components.py)

• Added get_error_count(name) method to retrieve error counts for specific components
• Includes proper null checks for component existence and attribute availability

Output Module (output.py)

• Enhanced record_status() method to track and persist error count in status entity attributes
• Error count increments on each error occurrence and persists across restarts

Main Predbat (predbat.py)

• Added component_error_count tracking in component health monitoring
• Component error counts are included in predbat.components entity attributes

Web Interface (web.py)

• Added error count display to component cards on the Components page
• Color-coded display: green for 0 errors, red for >0 errors
• Only displays when error count is available

Web Helper CSS (web_helper.py)

• Added .error-count-none class (green) for components with no errors
• Added .error-count-high class (red) for components with errors
• Includes both light and dark mode styling

Octopus API (octopus.py)

• Removed noisy debug logging from run method

Features

• ✅ Real-time error tracking for all components
• ✅ Visual feedback in web UI with color coding
• ✅ Persistent error count storage in entity attributes
• ✅ Dark mode support for UI elements
• ✅ Defensive programming with null checks throughout

Testing

• ✅ All pre-commit checks passed
• ✅ All unit tests passed (5.12s total)
• ✅ Manual testing confirmed error counts display correctly

Screenshots

Error counts are displayed on each component card in the Components view, providing immediate visibility into component health and making it easier to identify components experiencing issues.

Pull request overview

This PR adds comprehensive error tracking for Predbat components with visual display in the web UI. The implementation tracks both component-level errors (new) and enhances the main status error count to persist across restarts. Error counts are displayed in the web interface with color coding (green for no errors, red for errors) to provide immediate visibility into component health.

Key Changes

• Component error tracking infrastructure in ComponentBase with automatic increment on run failures and exceptions
• Error count retrieval methods in Components class with defensive null checks
• Enhanced web UI to display component error counts with color-coded visual feedback
